Dongguan Zhuo Li word luminous resin light guide plate agents, dispersants, dodging agents

Epoxy light diffusing agent is a liquid paste containing epoxy resin and efficient diffusion filler. Generally based on epoxy resin (A glue) 3-10% by weight (specifically, the amount of the recommendations and requirements based on the use of technology to add), the ratio added. Mainly applies to: LED resin luminous characters, LED luminous resin, a light emitting diode (LED package), LED digital tube, LED dot matrix, electronic display boards, light boxes advertising board, cosmetics bottles products, photoelectric products to increase light scattering and transmission while covering a light source and dazzling light, but also make the whole resin as a more gentle, beautiful, elegant light, to translucent opaque comfort effect. <1> General performance models: the proliferation of agents (Dodging agent) appearance (color): white to pale yellow pasty liquid Viscosity (25 ℃): 1200-1500cps Retention period: 6 months (25 ℃, sealed) <2> Use epoxy resin (A gum) substrate prior to addition of the curing agent (B gum) were mixed, was added about 3-10% of the diffusing agent and other material required to join the attachment (such as pigments, diluents, phosphor, etc.) at room temperature stir, then add curing agent, complete the curing of epoxy resins.  satisfy word luminous resin translucent opaque dodging effect conditions (1) high refractive index of the light diffusing agent refractive index than the resin. We used the light refractive index of 1.544 epoxy resin, acrylic resin, the refractive index of the light is 1.4910. Too much higher or lower than the refractive index of the resin will cause a lot of light reflection, affecting the light transmittance, a refractive index close to the resin, will reduce the light scattering path, fell less transparency, can not effectively shield light. (2) particle size of the light diffusing agent is greater than the wavelength of visible light. Since the diameter of the light diffusing agent than the wavelength of visible light (0.4 ~ 0.75um) large, so that the resin was dispersed in a sufficient amount of light diffusing agent can effectively shield the light source, and the distance between two adjacent light-diffusing particles is between small. Therefore, to produce multiple scattering of incident light becomes so bright affinity human eye Yunhe soft. "4" Note 1, add a light source is too small to see, add relatively dim light will emit excessive, it is recommended to first use a small amount of friends to do some testing before batch with; 2, please note that sealed after use Save.
